Sydney, New South Wales, Australia Application August 3, 1932, Serial No.

In Australia August' 19, 1931 the registrations on the ticket machines, and the other integrators in the group respectively sum up the individual horse totals. Such an integrating' l5 mechanism is the subject of the present application. l 'I'he third unit is a gear box which is connected up to the grand total integrator above-mentioned.

In this gear box certain deductions are made from the grand total, and the remaining total is proportioned according to the required dividend system on which thebetting is being conducted. This unit is the subject of our co-pending United States application Serial No. 627,371 filed August 3, 1932. The summation of the movements in the gear box is applied to a grand to al indicator and also tothe shaft of a master se f-synchronizing motor. This motor is wired in series with a plurality of distant self-synchronizing motors, each of which respectively operates a distant grand total indicator.

'I'he fourth unit vis a group of ratio or odds computing and indicating devices in which the ratio ofthe adjusted grand total in relation to the respective horse totals is transformed into a mechanical movement and displayed as .odds. Each computer is connected up to one of the horse total integrators above-mentioned, and all of them are connected up to the grand total gear box 40 above-mentioned. This unit is the subject of our co-pending United States application No. 627,370 led August 3, 1932. v

'I'he fifth unit of the series comprises a control station from which a plurality of distant indicators is operated. 'I'his unit is the subject of our co-pending United States application Seriah No. 627,371 filed August 3, 1 932.

One of the objects of the invention -is to provide an efficientv totalizator apparatus which is conchange to vary their capacityfand thus lmal-re each of these iigures certain structed in interchangeable units of moderate di- 2 Claims. (Cl. 235-92) them usable with equal advantage for either a small volume of business or a. large volume of business. y

Hitherto totalizators of the type to which this invention belorigs have consisted in effect of a 5 number of ticket issuing machines connected up to a ponderous assembly of mechanism which was of such a character that when once erected it had toremain as a permanent installation. For this reason itwas impracticable to provide an eicient 10 totalizator for courses which call for its use only at long intervals and for short periods. L 'The integrating mechanism which is the subject of the pr sent application is illustrated in the accompany g drawings, in'whichr- Fig. 1 is a. vertical sectional elevation, and Fig, 2* a plan view of one horse total integrator. In parts are omitted to simplify the drawings;

Fig. 3 isa fragmentary end elevational view 20 of portion of the unit shown in Fig. 2. This view shows a change-over arrangement for controlling the rate of transmission from the integrator to the associated computer and indicator; this arrangement makes it-practicable to construct all 25 these mechanisms to standard dimensions and to vary their capacity by a gear change;

Fig. is a sectional elevation on the plane of 40 the line 5--5 in Fig, 2; and

Fig. 8 is a diagram of the gearing.

Initial drive is transmitted from a constantly running motor to each integrator through a belt pulley 220 which is connected to a shaft 22| 45 through a slipping clutch 222, 223 being the clutch spring. The main summation shaft 224 is driven from the shaft 22| through a pinion 225 which meshes with a spur wheel 226, the spur wheel 226 being keyed to the shaft 224. The rotation of 50 thev shaft 224 is permissive and is controlled through an epicyclicv box 21, the planet element of which is keyed at k228 to the shaft 224. The sun wheel 229 of the epicyclic box 221 carries on its sleeve 230 a spur wheel 23| which meshes with 55 AIn -the unit 2|3, |16 represents the escapements,

26| an alarm lamp, and |90 the cut-out relay which is actuated by the slip ring contacts |88- |69. The ticket machines are also connected up by the leads 2|4 to each of the horse total integrators 2 |5 in which'the escapements |16, relay |90 and slip ring contacts IBB-|69 are diagrammatically shown. One of the circuits through the ticket machine marked 2 |0E is shown completed.

The horse total integrators are connected tothe return line of the main circuit |51 through switches 2|6, by means of which any one or more of the integrators can be Acut out of the circuit. i

Other switches which control the circuit through the totalizator assembly are shown in the drawings, but as they are not part of the in vention they need not be described.

For example, if the relay |90 is short-circuited in the integrator marked 2|5A in Fig. 6, the circuit through the escapements |16 in that integrator will be opened and the circuit through the alarm lamp 26| and alarm bell 2 5B will be closed. As shown in Fig. 6 these escapements are electrically connected through the leads 2|4 with the left hand contact 2 |0A in each of the ticket issuing machines 2|0. Consequently if the circuit is opened at |90 in the integrator marked 2|5A, the circuit through the left hand contact in every ticket 7 suing machine will be cut out, and no more tickets can then be issued on the horse allocated to that integrator until the fault has been rectified and the relay |90 restored. The cutting.A out of one integrator in this manner does not affect the operation of any other integrator in the system nor the issue of tickets in respect of any other integrator.

On the back end of the summation shaft 224 a spur wheel 263 is keyed; this spur wheel meshes with a spur wheel 264 which is keyed to a shaft v265 (Fig. 2). Three sprocket wheels 266, 261, 268

of different diameters are iixed on a clutch member 200 which is axially slidable on the shaft 265. One or other of these wheels is connected (see Fig. 3) by a chain 269 to mechanism by which an indicator is operated, or otherwise to a ratio computer and odds indicating mechanism of the type described in our co-pending United States application Serial No. 627,370. The chain 269 is under tension of a weight 210 and it is readily movable across from any one of the sprockets 266-261-268 to any other of them; when it is meshed with the sprocket 266 the range of movement applied to the chain 269 and by that chain to the indicatorV mechanism will be a maximum for 'any given number of rotations of the shaft 265, whilst when it is meshed on the sprocket 268 that movement will be a minimum. Transfer at intermediate rate is obtained when the chain is meshed on the sprocket 261.

This arrangement facilitates the utilization of the apparatus for either large or small race courses, so as to obtain maximum accuracy in the indications given by the indicator,. for this reason. Where the number of tickets issued is comparatively small, the range -of movement of the computing elements in the indicator apparatus would be correspondingly small, and consequently the lost motion and mechanical inaccuracies in transmission might account for a slight variation in the correctness in the figure displayed on the indicators. In such circumstances, it is desirable that the range of movement of the elements in the indicator apparatus should be magnified. 1n This magnication is readily obtained by placing the chain 269 on the large sprocket 266 in each computer. When heavy betting is expected which would result in more extensive movements in the indicator, the transmission is geared down by placing the chains 269 on the small sprockets 268. v

The change over of the chain 269 from one sprocket 266-261-268 to the other is accompanied by an automatic change in the circuiting arrangement; this change is effected by carrying the chain 269 under an idle pulley |9| and over a jockey roller 21| which is carried on one end of a spring loaded rocking switch arm 212. A spring |92 holds the arm 212 steady, with the roller 21| 25 in contact with the chain 269. According to the sprocket on which the chainl269 is engaged, the switch arm 212 is caused to close a circuit through one of three pairs of contacts 213, 214, 215. The switches 212 and contacts 213-214-215 in three integrators A-B-C are indicated diagrammatically in'Fig. 4.' When the manager, foreseeing the amount of betting which will take place on the next race, sets his control switch 216 on one or other of the circuits shown in Fig. 4, the correspending signal lamp 219 in that circuit lights up, and with it also the signal lamp 280 in the operators room to indicate to the operator which particular circuit is required to be operated. 'I'he operator then shifts over the chains 269 in each 40 of the integrators thus at the same time setting the switches 212 in those integrators. This gear change necessitates a corresponding lreadjustment in the grand total integrator mechanism,

which is shown diagrammatically positioned yat 289, in Fig. 4. As all the machines are circuited Vin series, the response lamp 211 will not light up until the chain in every integrator has been correctly changed, ,and the grand total mechanism also correspondingly adjusted. When all the changes have ibeen made and the contacts have been thus closed,.the response lamp 211 in the operators box lights up, and the response lamp 218 in the managers room also lights up, and thus there is .an assurancel to both operator and 5 manager that the circuits are complete.

In the event of a particular integrator overrunning the full capacity of the ratio computing apparatus associated with it, owing to the number of bets registered being in excess of the capacity provided for, an automatic alarm is given to the operators, whose duty it is to throw that indicator apparatus out of circuit. 'Ihis is 'eiected'by means ofthe clutch 200 shown in Fig. 2. The operator releases this clutch by' turning back a 65 hand piece 288. A spring 295 then forces the cone faces 29| apartand thereby disconnects the drive of the shaft 265 and gear wheel 264 from the wheels 2,66-261-268. When the'handpiece 288 is thus run back to open the clutch, it is necessary P0 for the voperator to guard against return moveyment by inserting a peg 294 in a check hole in the shaft 265 as a spring 292 normally winds up the handpiece 288, so as to apply pressure at the cone faces 29|. 75

The opening of the clutch 200 thus disconnects the indicator mechanism, but it does not affect the operation of the integrator unit or the operation of the grand total mechanism, as the sum* mation of the registrations in each integrator is registered on a Veeder counter 296 which is directly geared to the main summation shaft 22d through the spur wheels 291 and 225. The counter 296 does not register units; the units are displayed on a drum indicator 298 which is geared up 10:1 in relation to the counter 295 by the spur gears ZIN-208. For the purpose of computing payments, the figures up to the tens are taken from the counter 296 and the unit figures `from the counter1 298.

An integrator such as has been described is used to integrate each horse total and to actuate a ratio computer connected with it. A similar mechanism with certain modications is used to integrate the grand total of all the horse totals.
